Format | Overview & Tips | Tools to use* | Compatible with this device(s) |
Microsoft Word (DOC/DOCX) | Most DOC/DOCX files convert well to eBooks. However, some files with complex formatting may not convert as well.
Use Kindle Previewer to check if your eBook converted successfully. For details on formatting, see our eBook Manuscript Formatting Guide. |
For details, visit Microsoft Support. |
|
Kindle Package Format (KPF) | Using KPF files allows your eBook to easily format an fit all Kindle devices. It’s a go-to method for avoiding any formatting issues.
You can create a KPF file using Kindle Create. What are the benefits of using Kindle Create?
If you want to change from reflowable to Print Replica or vice versa, you can unpublish the previous version and then add it as a new title using the desired format. |
For more information on how to install or use Kindle Create, check out our Getting Started with Kindle Create page. |

MOBI | We support books in MOBI format that meet the specifications outlined in the Kindle Publishing Guidelines.

Rich Text Format (RTF) | We support RTF files.
RTF is readable across many programs and platforms and it’s easy to use. |
|

Plain Text (TXT) | We support TXT files for manuscripts that do not contain images. Since KDP converts plain text to HTML, image locations referenced in a TXT file will not convert successfully. |

Adobe PDF (PDF) | We accept PDF files, but they can contain embedded formatting and/or images that don't convert well to eBooks.
At this time, KDP only supports uploaded PDFs in the following languages: English, French, German, Italian, Portuguese, Spanish, Catalan, Galician, and Basque. If you'd like to upload a PDF file for your book, preview it before you publish. If you see any issues or if your book doesn't look the way you want it to, we recommend converting your PDF to a Word document and formatting it according to our eBook Formatting Guide. You can also try using Kindle Create. |
